Active carbon

Abstract

The application belongs to the technical field of chemical industry production, and particularly relates to an active carbon. At present, coal tar is used in the production of the active carbon and the active coke and causes serious atmospheric pollution, and meanwhile, the human body is injured on a certain degree in the production process. The application provides the active carbon, and the active carbon comprises the following components by weight: 100-120 parts of coal, 10-35 parts of high-temperature modified asphalt, and 5-20 parts of starch. The coal, the high-temperature modified asphalt, and the starch are mixed at certain proportion, a starch coal tar substitute product is used to prepare the active carbon, the atmospheric environment is improved, the pollution is reduced, so that the preparation of the active carbon is more environmentally friendly, and meanwhile, the cost is lower.

Description

technical field [0001] The application belongs to the technical field of chemical production, in particular to an activated carbon. Background technique [0002] Activated carbon is a porous artificial carbon adsorbent made of carbon-containing substances after carbonization and activation. It has a well-developed pore structure and a huge specific surface area, and can be used as an adsorbent, catalyst and catalyst carrier. Activated carbon, as a man-made material, was invented from 1900 to 1901. Its inventor was Rafael Wang Osterleko, who obtained a patent by using chemical activation and physical activation to manufacture activated carbon. Activated carbon was produced industrially for the first time in 1911 by Dr. Mengaud at his factory near Vienna. The product at that time was powdered activated carbon, which was the first industrial production plant in the world. [0003] Activated carbon is the qualified raw coal of Taixi anthracite as the main raw material. After ...
